Fat Intake After Diagnosis and Risk of Lethal Prostate Cancer and All-Cause Mortality

IMPORTANCE Nearly 2.5 million men currently live with prostate cancer in the United States, yet little is known about the association between diet after diagnosis and prostate cancer progression and overall mortality.

CONCLUSIONS AND RELEVANCE Among men with nonmetastatic prostate cancer, replacing carbohydrates and animal fat with vegetable fat may reduce the risk of all-cause mortality. The potential benefit of vegetable fat for prostate cancer-specific outcomes merits further research.
